3 Phase 1000kVA 1200kVA 1500kVA 2000kVA 2500kVA Stamford Brushless Generator Alternator

Insulation And Varnish:
The insulation system is class H.
All wound components are impregnated with materials and processes designed specifically ensure the generator running in dreadful conditions. The special developed resin materials meet rotating components.

Windings and Electrical Performance:
All generator stators are wound to 2/3 pitch, This eliminates triple(3^rd,9^th,15^th…)harmonics on the voltage waveform and is an optimum designed for UPS equipment of non linear loads. The 2/3 pitch design avoids excessive neutral currents result from higher winding pitches. A fully consecutive damper winding reduces oscillations during paralleling. The 2/3 pitch windings and carefully pole and tooth ensures very low waveform distortion.

Terminals And Terminal Box:
Standard generators are 3-phase,and you can reconnect 12 ends of the terminals, which are mounted on a terminal block at the non-drive end of the generator. A sheet steel terminal box within AVR is provided with enough place for the customers'wiring. It has removable panels for easy access.

Telephone Influence Factor:
THF(BS EN60034-1)<2%
THF(NEMA MG1-22)<50

SHAFT AND KEY
All generator rotors are dynamically balanced to better than minimum vibration of BS6861: part1 grade 2.5 double bearings generators are banlanced with a half key.

ENGINE ADAPTOR AND COUPLING

All generators are designed two kinds of construction. The adaptor and the drive plate is consonant with SAE standard.

LEVELS Of PROTECTION

All generators are IP2 and IP23 and IP44 can be optional for aircool protected generator. but rated power will decrease 5~10%.
The Definition Of The Product Model:

Alternator Features:
 
1)Advanced automatic voltage regulator control for trouble-free operation under the most demanding condition
2)Easy paralleling with mains or other generators .Standard 2/3 pitch windings avoid excessive neutral currents.
3) Dynamically balanced rotor, with sealed-for-life ball bearings and single or two-bearing construction.
4)Simple installation and maintenance with easy access to terminals, rotating diodes and coupling bolts.
5)Wide range of Flange adaptor and single bearing coupling disc.
 
All of alternator rotors should pass balance test, whose vibrations are lower than the minimum of BS6861 P.1,G 2.5 two bearing alternator has a half-key testing balance
 
Terminal and terminal box
 
The three-field alternator had 12 leads brought out to the terminals in the terminal box. The terminals are put on the non drive end . The box is equipped with removable panels.
 
Winding and electric features
 
2/3 pith winding design can effectively eliminate the third harmonic wave(3th.9th,15th) of the voltage ,which is the best design of UPS for nonlinear load .Connected with the network in parallel, the structure can restrain excessive currents in the midline. This and the 2/3 pitch help to check the wave distortion and output voltage.
